MACHINE FOR STAMPING CIGARS.

SPECIFICATION forming part of Letters Patent No. 455,820, dated July 14,1891- Application filed October 8, 1890. Serial No. 867.400. (No model.)

To aZZ whom it may concern.-

Be it known that we, GEORGE F. MCINDOE and JAMES W. MCINDOE, both ofBoston, in the county of Suffolk and State of Massachusetts, haveinvented, jointly, new and useful Improvements in Machines for StampingCigars, of which the following, taken in connection with theaccompanying drawings, is a specification.

Our invention relates to machines for impressing letters, figures, orotherdesigns upon cigars; and it consists in certain novel features ofconstruction, arrangement, and combination of parts, which will bereadily understood by reference to the description of the accompanyingdrawings, and to the 91311118 hereinafter given andin which ourlnvention is clearly pointed out.

Figure 1 of the drawings is a side elevation of a machine embodying ourinvention. Fig. 2 is avertical sectional elevation, the cutting planebeingon line as a: on Figs. 3 and 4with one of the die-holders removedand a portion of one of the tubes of the gas-burner broken away, inorder the better to show otherparts. Fig. 3 is a sectional plan, thecutting plane being on line y 3 on Figs. 1 and 2. Fig. 4 is a sectionalplan, the cutting plane being on line z 2 on Figs. 1 and 2. Figs. 5 and6 are respectively a side elevation and an inverted plan of one of thedie-holders. Fig. 7 is an inside elevation of one of the cigar-holdingforks and a portion of its carrier, and Fig. 8 is a section of saidcarrier on line '0 1; on Fig. 7 and showing the cigar-holding fork inelevation. I

In the drawings, A is the base portion of the frame of the machine,provided with the legs A, and B is the upper portion of the frame,having formed integral therewith the archlike support 13 for theoperating-lever O.

Theuppcr part of the base portion of the frame has cast therein twocross-ties a a, each having formed in its upper edge a vertical slot ato receive one of the trunnions Z) of the die-holder D, the oppositetrunnion of said holder fitting into a similar slot 1), formed in a lug12 east upon the inner face of the outer shell of said base, as shown inFig. 4.

The two sides of the base A that are at right angles to the ties at ahave cast thereon inwardly-projecting flanges E E, in each of ranged tobear and act one upon each end of said die-holder, so that by turningsaid screws said die-holder may be adjusted relative to theimpression-pad to adaptit to cigars of varying tapers.

Each of the flanges E has formed therein equidistant from the ties at aan open slot (Z to receive a clamping-bolt e, which extends upwardthrough a slot f in the lug g, cast upon the inner surface of the upperportion B of the frame, the upper surface of said lug 9 being providedwith lips 9, between which the rectangular head e of the bolt e fits, sothat it cannot revolve when the nut e is being turned. v

The two portions A and B of the frame are separated from each otherbyaspace of about one-eighth of an inch (more or less) by means ofwashers or blocks 6 of asbestus or other non-heat-conducting material,for the purpose of preventing the heat from the gas-jet beingtransmitted to the upper frame and to the opcrating parts of the machinecarried thereby.

The die-holders D D are supported entirely by the lower or base portionof the frame, and each has formed therein a longitudinal slot h,extending to its upper surface, in which is formed a shallowlongitudinally-dovetailed groove 72' to receive and hold the die-plate712, all as shown in Figs. 2 and 6.

The frame 13 has mounted thereon two rocking frames F F, the axes ofwhich are parallel to the die-holders D D and between said die-holdersand the sides of said frame B.

The rocking frames F F each comprise a rocker-shaft or its equivalent,two radial arms '1' i, projecting inward therefrom,.one at each end ofthe die-holder D and each provided at its inner end with a hub t, acrank pin or lug j, projecting from one of said radial arms parallel tothe axis of said frame, a stop-shoulder 7c to limit the oscillationof'said frame in one frame 1% inside of said ears Z, as shown in' Fig.1.

The hubs q t are bored out to form bearings for the stems of thecigar-supports m m, said stems being provided with shoulders at, whichrest upon spiral springs n, surrounding the smallerportion of said stemand serving to move said supports upward when the pressure is removedand allow said supports to be depressed when the pressure is applied tothe cigar by the impression-pads G and G. The supports m are preventedfrom turning in their bearings by the pins 0, which project from theirstems through the slots formed in the hubs t" i, and the upwardmovements of said supports are limited by stop-pins 0 all as shown inFigs. 7 and S.

The impression-pads G and G are made concavo-convex in cross-section andare each provided with a pair of inwardly-projecting arms H II, one ateach end, and with a pair of ears p p at or near the center of itslength and projecting upward therefrom, as shown. The arms H of the padG are firmly secured upon the rocker-shaft I, mounted in bearings V inthe upright portions of the arch B, and

the inner ends of the arms II of the pad G are loosely mounted on saidshaft.

0 is a hand-lever pivoted at q in the arch B and pivoted at its lowerend to the upper ends of two links K and K, the lower ends of which arepivoted, respectively, to the ears of the pads G and G as shown in Fig.2. The shaft I projects at one end beyond the frame B, and has firmlysecured thereon, so as to oscillate therewith, the two-armed lever L,having secured upon each arm thereof a leafspring L, the free end ofwhich projects beyond the end of the lever-arm, as shown in Fig. 1.

M is a gas-burner of the Bunsen form, provided with a supply-pipe r andtwo curved pipes s s to direct a portion of the flame therefrom to theinterior of each of the die-holders directly beneath the die-plates.

It should be understood that a die-holder is mounted at the right-handside of Fig. 2, precisely like that shown at the left-hand side of saidfigure, it being omitted for the purpose of showing parts that would behid by it if in 1 position.

, The two sides of the machine are perfectly symmetrical and aredouble-actingthat is, each movement of the hand-lever will cause thestamping of a cigar, provided they are supplied to the supports 1% asfast as required.

The operation of our invention is as follows: The parts being in theposit-ions shown in Figs. 1 and 2 and the dies and die-holders beingadjusted to the proper heights and angles relative to the pads G and G,a cigar is placed in the forked supports an beneath the pad G. The upperend of the lever C is moved toward the left of Figs. 1 and 2, therebydepressing the pad G, causing it to press the cigar upon the die beneathit and impress in its under.

side the letters, figures, or other, designs formed thereon. The samemovement of the lever G raises the pad G and moves the twoarmed lever L,so as to depress the right-hand arm and carry the spring L, securedthereto, below the pin j of the right-hand rocking frame F and carry theleft-hand arm and its spring above the pin j of the left-hand rockingframe F. forked supports m'beneath the pad G,when the upper end of thelever O is moved to the right, depressing the pad G and raising the padG, when the last cigar will. be stamped. The one first stamped will beraised from the die by the action of the springs 07. upon the forkedsupports m at the right of Figs. 1 and 2, which springs n are shown inFig. 8, and at the same time the lever L is vibrated, and the end of thespring L, secured to the righthand arm thereof, coming in contact withthe pin j of the right-hand rocking frame F, moves it into the positionindicated by dotted lines in Fig. 2, and the cigar held in the supportsm is discharged therefrom, and the spring L, attached to the left-handarm of the lever L, is carried below the pin 3' of the left-hand rockingarm, said spring yielding to allow it to pass said pin. Just before thecompletion of the movement of lever L toward the right the end of thespring L at that side passes the pin j, and the rocking frame F, thathas just been 'raised thereby, falls back to its normal position, asshown in full lines.

By making the machine with two dies, so as to be double-acting, andholding the impression on one cigar during the time necessary to place acigar on the opposite pair of holders, a much better impression of theletters is formed in the cigar than would otherwise be the case, thelonger subjectionto contact with the hot die serving to set theimpression.

W' e claim 1. In a cigar-stamping machine, the combination of astationary die, a pair of yielding cigar-supports arranged one at eachend of said die, a vibrating impression-pad, and a hand-lever andtoggle-link for operating the same.

2.
